The Offer
The Upgrade account has $300 signup bonus for new customers who sign up for their Rewards Checking Plus account using a referral link and direct deposit at least $1,000 in 45 days.
The referrer gets $100.
Our Verdict
Not all links are showing the $300 offer, many are. Previous offers were just $150-$200 for new member and $50 for referrer, so this deal is significantly better. (See this comment about other stacking discussions.)
Do not post a referral link in the comments below. You can find referrals on this dedicated page. Follow instructions there carefully.
